AGRIC PRACTICAL 9.30AM – 11.00AM
Experiment to compare the porosity and water holding capacity
Grind loam and clay soil into fine particles, after drying in the sun. Equal masses of the dry, dry clay and dry loam are place seperately into three funnels which are blocked at the neck with cotton wool. The three funnels containing different types of soil are then placed on top of the three measuring cylinders. Then quickly pour equal amount of water into the funnels, containing each soil type. Then leave for an hour
i)I will ensure th three funnels containing different types of soil are placed on top of the three measuring cylinders
ii)I will ensure equal amount of water is quickly poured into the funnels containing th soil type
Because the porosity is high in sandy soil because of large pores spaces and larger particles sizes
